cation phere.

Be it known that I, THOMAS TAYLOR, of the city and county of Washington, District of Columbia, have inventeda new and Improved Fertilizer, of which the following is a specifi- My invention relates to an improvement in fertilizers and con sists in a new combination of night-soil with other nsefulingredients, and

is composed as follows, viz:

Night-soil, peat, persalt of iron, clay, soluble silicates, and tincture of quassia, which I compound in thefollowing manner:

I first prepare a solution of a persalt of iron by any of thewell-known modes, which I use F as a deodorizer of night-soil. I add the persalt to the night-soil, and mix thoroughly, or

until the mass is deodorized of all excreta odor. To this I add. ground peat and ground clay, (deodorizers and absorbers of moisture,)

soluble silicates, and the tincture of quassia. I combine the whole properly by suitable machinery, after whichl placethe compound under cover, to dry by exposure to a dry atmos- Y The mixture is next ground into a fine powder, when it is fit for use.

I am aware that sulphate of iron has been long used as a deodorizer of night-soil; but it is found in practice not to be an effectual deodorizer, except when free ammonia is present inthe compound, while the persalt of iron decomposes the sulphureted hydrogen at all when present.

Sulphureted hydrogen converts a persalt into aprotosalt with precipitation of sulphur, page 562 Elements of Chemistry, (Grahm) Gopperas, therefore, is not decomposed by the sulphureted hydrogen of night-soil, and in this my claim differs from Mr. Fishs two patents. I therefore do not use the same deodorizer used by Mr. Fish in his patents of July 20 and August 11, 1869, and which contain common salt, peat ashes, charcoal, gypsum, tincture of almonds, tincture of cofl'ee, and coffee-grounds, substances which 1 neither claim nor use. v v

WhatI claim, and desire to secure by Letters Patent. ise lhe combination of night-soil with peat, clay, soluble silicates, a 'persalt of iron, and tincture of quassia, in all proportions, when combined substantially in the manner and for the purpose as set forth and described.

THOMAS v TAYLOR.
